Now all smartphones have unique features but when we are charging our smart samsung phone must give us a Alarm at the finishing time of charging so as to avoide excess charges which might damage battery and use of unnecessary electricity can be saved.
We don't have to see again and again what is % of charging is finished if it Alarms.
It is something which is good to have, but let me tell you that you need not worry about overcharging and damaging your battery, or wastage of unnecessary electricity. Your device, its battery and charger, all are smart and nothing of the things you are worrying about will happen.
